SPECIFICATION forming part of Letters Patent No. 749,242, dated January 12, 1904.

Application filed April 24, 1903. Serial No. 154,054. (No model.)

To all whom it may concern:

Be it known that I, J USTUS A. TRAUT, a citizen of the United States, residing at New Britain, Hartford county, Connecticut, have invented certain new and useful Improvements in Miter-Boxes, of which the following is a full, clear, and exact description.

My invention relates to improvements in miterboxes, and particularly to the saw guide and, carrier portion thereof.

In miter-boxes it is customary to provide guides for the saw. Saw-carriers are also provided which move up and down with the saw on the guides. These carriers have usually been mounted loosely upon the guides, so that when not held Lip-manually they drop to and rest on the bottom of the guide. In this position it is diflicult to insert a saw. I have provided simple and efiective mechanism whereby each carrier will remain stationary on its guide at whatever elevation it is left. In addition to this I have provided further means whereby the carrier will be held in its uppermost position with the saw in place andwhen the saw is idle. This pe'rmits the ready insertion of new work without removing the saw or without the necessity of manually holding the same.

In the accompanying drawings, Figure 1 is a front elevation of a saw guide and carrier constructed to embody my invention. Fig. 2 is a side elevation of the upper portion of the part shown in Fig. 1. Fig. 3 is a section on the line 3 3, Fig; 2.

I have shown in the drawings only such parts of a miter-box as are necessary to a full understanding ofthe construction and operation of my invention. A full illustration of a completemiter-box'may, however, be seen in the accompanying application, Serial No. 154,051, filed April 24, 1903.

In the particular form shown herein the sawguide comprises two posts 1 1, while the sawcarrier comprises a body 2, having a vertical slot to receive the saw-blade, which slot is enlarged at or near the upper end, as at 3, to receive the saw-back.

4 is a spring-controlled sliding latch mounted in I a guideway extending transversely through the cylindrical carrier 2 and above- The greatest width of the latch 4L exceeds the space between the guide-posts 1 '1; but a notch is provided in each opposite edge of said latch, so that when the slide is in a certain position the notches will register with the posts and the carrier may be moved up and down freely.-

This certain position is an abnormal one, however, it being necessary to press against the end of the latch to shift it against the normal tend-w ency of the spring 5. In Fig. 3, however, it y will be seen the edges of the latch adjacent to the notches therein are in positive engagement in notches 7 7 in the guide-posts 1 1. These notches 7 7 are provided near the upper ends of the guides 1 1, so that when the carrier 2 is raised to its uppermost position it will be positively locked against descent. It is customary to provide in a miter-box a pair of saw guides and carriers,- and each of them is preferably provided with this locking arrangement. The power of the spring 5 is preferably such as to cause enough frictional resistance between the latch 4: and the guides 1 1 to hold the carrier suspended at any desired elevation when the saw is removed. Hence the user may readily insert the saw without manually-elevating the same.

What I claim is 1. A saw guide and'carrier for a miter-box comprising guide posts, a carrier frame mounted to slide up and down thereon, and

means carried by said carrier-frame for frictionally holding said carrier at any elevation on said supporting-posts, and a notch in one of said supporting-posts adapted to receive said adjusting means and positively lock the same inits elevated position.

2. A saw guide and carrier for a miter-box comprising a pair of guide-posts spacedapart and in parallel arrangement, a reciprocating saw-carrier frame mounted on said guideposts, a slide arranged transversely thereof the greatest width of said slide being in excess of the space between said guide-posts, notches in said slide arranged to register with said guide-posts when in one position to admit of the carrier being raised and lowered, a spring exerting constant pressure against said slide to cause a frictional engagement between said slide and said posts whereby the carrier is frictionally held at any desired elevation on said posts.

3. A saw guide and carrier for a miter-box comprising a pair of guide-posts spaced apart and in parallel arrangement, a reciprocating saw-carrier frame mounted on said guideposts, a slide arranged transversely thereof the greatest width of said slide being in excess of the space between said guide-posts, notches in said slide arranged to register with said guide-posts when in one position to admit of the carrier being raised and lowered, a spring exerting constant pressure against said slide to cause a frictional engagement be.- tween said slide and said posts whereby the carrier is frictionally held at any desired elevation on said posts, and a notch in one of said guide-posts near the upper end thereof of a sufficient size to receive a portion of the slide and positively lock said carrier in its elevated position.

Signed at New Britain, Connecticut, this 3d day of April, 1903.
